# DecimalFormatSymbols

`public class DecimalFormatSymbols`
`extends Object` `implements Cloneable, Serializable`

java.lang.Object
↳ | java.text.DecimalFormatSymbols

This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed by `DecimalFormat` to format numbers. `DecimalFormat` creates for itself an instance of `DecimalFormatSymbols` from its locale data. If you need to change any of these symbols, you can get the `DecimalFormatSymbols` object from your `DecimalFormat` and modify it.

See also:

- `Locale`
- `DecimalFormat`

## Public constructors

### DecimalFormatSymbols

    public DecimalFormatSymbols ()

Create a DecimalFormatSymbols object for the default `FORMAT` locale. It is recommended that the `getInstance` method is used instead.

This is equivalent to calling `DecimalFormatSymbols(Locale.getDefault(Locale.Category.FORMAT))`.

See also:

- `Locale.getDefault(java.util.Locale.Category)`
- `Locale.Category.FORMAT`

### DecimalFormatSymbols

    public DecimalFormatSymbols (Locale locale)

Create a DecimalFormatSymbols object for the given locale. It is recommended that the `getInstance` method is used instead. If the specified locale contains the `Locale.UNICODE_LOCALE_EXTENSION` for the numbering system, the instance is initialized with the specified numbering system if the JRE implementation supports it. For example,

     NumberFormat.getNumberInstance(Locale.forLanguageTag("th-TH-u-nu-thai"))

This may return a `NumberFormat` instance with the Thai numbering system, instead of the Latin numbering system.

Parameters
`locale` | `Locale`: the desired locale

Throws
`NullPointerException` | if `locale` is null

## Public methods

### clone

    public Object clone ()

Standard override.

Returns
`Object` | a clone of this instance.
